REQUIRED: Add Akida Runtime to LD_LIBRARY_PATH

For PySDK to locate Akida Runtime, LD_LIBRARY_PATH must include the Akida Runtime library path.

Temporary Setup

To set LD_LIBRARY_PATH for the current terminal session, run the following command: 

export LD_LIBRARY_PATH="$(python3 -c "import akida, os; print(os.path.dirname(akida.__file__))"):$LD_LIBRARY_PATH"

Permanent Setup

To make this change persistent, we find the Akida Runtime path and then add it to ~/.bashrc. Run the following commands: 

AKIDA_PATH=$(python3 -c 'import akida, os; print(os.path.dirname(akida.__file__))')
echo 'export LD_LIBRARY_PATH="'$AKIDA_PATH':$LD_LIBRARY_PATH"' >> ~/.bashrc
source ~/.bashrc

Troubleshooting

If no Brainchip device is detected in degirum sys-info output, please see the permanent setup instructions here.

If no Brainchip device is detected in akida devices output, you may need to (re)install the Akida PCIe driver.

Driver Installation

Driver Installation is done through a script provided by Brainchip in their GitHub repository:

git clone https://github.com/Brainchip-Inc/akida_dw_edma
cd akida_dw_edma
sudo ./install.sh

After installation, check the device list again:
